采用氨基酸自动分析仪测定分析了茗科1号和金牡丹工夫红茶游离氨基酸组分，结果表明：茗科1号工夫红茶游离氨基酸总量为38.43 mg/g，金牡丹工夫红茶为37.20 mg/g。含量较高的氨基酸组分为茶氨酸、谷氨酸、天冬氨酸、丝氨酸，其中茗科1号工夫红茶茶氨酸比例为（73.02±3.63）%，金牡丹工夫红茶茶氨酸比例为（66.82±7.94）%。茗科1号和金牡丹工夫红茶的氨基酸组分含量总体差异较小，与铁观音工夫红茶均有较大差异。通过主成分分析结果表明，丙氨酸、苏氨酸、丝氨酸和赖氨酸可以作为金牡丹工夫红茶区分茗科1号、铁观音工夫红茶的氨基酸特征组分；半胱氨酸、天冬氨酸及酪氨酸可以作为茗科1号工夫红茶区分金牡丹、铁观音工夫红茶的氨基酸特征组分。

The compositions of free amino acids of congou black teas, which were made by cultivarsMingke 1(Camellia Sinensis) andJinmudan(Camellia Sinensis) have been analyzed in the study by using automatic amino acid analyzer. The results showed that the total amount of free amino acids inMingke 1 andJinmudancongou black teas were 38.43mg/g and 37.20 mg/g, respectively. In general, the contents of theanine, glutamic acid, aspartic acid and serine were higher than other amino acid components in the two congou black teas. Theanine accounted for(73.02±3.63)% of total amino acids in Mingke 1 congou black teas and(66.82±7.94)% inJinmudan congou black teas. As for the contents of amino acid constituents, small difference was observed betweenMingke 1 and Jinmudan congou black tea, but both of them showed a large difference comparing toTie guanyin(Camellia Sinensis)congou black tea. Furthermore, the principal component analysis results showed that the lanine, threonine, serine and lysine are the characteristic components of amino acids to distinguishJinmudan congou black teas fromMingke 1 andTie guanyin congou black teas. On the other hand, the cysteine, aspartic acid and tyrosine, as the characteristic components of amino acids, could be used in distinguishingMingke 1 congou black teas fromJinmudan andTie guanyincongou black teas.
